Pre-treatment:Always ensure all surfaces are clean, oil-free, and dry. Clean the surface and remove any oil and grease with a suitable cleaner, then sand the surface with dry sandpaper. Carefully remove dust with fresh water.
Painting:Fiberglass:
Sand the surface and remove dust.Steel:
Remove salt and other impurities by cleaning (high-pressure) with fresh water. Remove all rust and loose material by blast cleaning or wire brushing. Remove dust.Aluminum:
Wash with fresh water and a pressure washer. Blast clean without metallic abrasives. Sand, clean, and dry the surface.Plywood:Sand the surface and remove dust. Seal the dry and clean surface with suitableHempel Sealer 599
.Previously treated surface:
Sand, clean, and dry the surface.
Painting:Unpainted surfaces below the waterline:Prime porous surfaces by thinning the product used for the first coat as specified withHempel Thinner 845
: max. 20%. Apply a total of 3-5 coats to achieve full film thickness. Add thinner if necessary: max. 5%. Overcoat with specified HEMPEL primer/adhesion primer and selected antifouling paint while the product is still tacky. It is crucial to prime aluminum surfaces with a total dry film thickness of at least 300 microns.Unpainted surfaces above the waterline:Prime porous surfaces by thinning the product used for the first coat as specified withHempel Thinner 845
: max. 20%. Finally, apply 2 coats of the product. Add thinner if necessary: max. 5%. Overcoat with selected topcoat.Previously treated surface:
Sand, clean, and dry the surface. Apply 1 coat of the product. Add thinner if necessary, max. 5%. Overcoat with selected topcoat.Mixing ratio:
2:1 by volume. Mix the base and add the hardener. Mix thoroughly. After mixing the paint, wait several minutes for air bubbles to disappear. Previous paint layer:Hempel's Sealer
